What is the outermost layer of the Earth called?

• Mantle

• Core

• Crust

• Lithosphere

Which layer of the Earth is composed mostly of solid rock and is located directly below the crust?

• Core

• Mantle

• Lithosphere

• Asthenosphere

What is the innermost layer of the Earth called?

• Outer Core

• Mantle

• Inner Core

• Lithosphere

Igneous rocks are formed by:

• Compaction and cementation of sediments

• Cooling and solidification of magma or lava

• Heat and pressure applied to existing rocks

• Deposition of mineral grains by water, wind, or ice

Metamorphic rocks are formed from other rocks by the process of:

• Cooling and solidification

• Compaction and cementation

• Heat and pressure

• Melting and solidification

The lithosphere consists of:

• The crust and the uppermost part of the mantle

• The entire mantle

• The crust only

• The crust and the core

The asthenosphere is:

• A stable solid layer below the lithosphere

• A partially molten layer upon which the lithosphere floats

• The solid outer core of the Earth

• The layer consisting of the crust only

The process by which sedimentary rocks are formed is known as:

• Metamorphism

• Compaction and cementation

• Crystallization

• Subduction
